Aqua Connect's HIT 14,000K+ MH bulbs are newly invented after long-term study by professors and researchers. They genuinely simulate near-Nature light spectrum for brilliant color reproduction, enhance excellent coral growth, and increase long-term color stability. HIT bulb is the result of a new German burner technology so that your aquarium looks more realistic than ever before. 14,000K HIT light contains very high percentage of the blue spectrum to simulate the natural light condition of coral reef. It provides a substantial improvement over 10,000K bulb while eliminating the need for 20,000K one.
